Severity is set to medium. That said, this is a general guide. Depending on your particular symptoms and faults, the severity will vary significantly. Generally speaking though, any hydraulic issue or anything to do with internal engine systems, I tend to recommend repairing the issue as soon as possible. Not really an area of the vehicle you want to neglect, so get it diagnosed and repaired, by a professional if you have to!
